Ok, So what is a Ketogenic Diet All About?!
A Ketogenic diet (often called Keto) is a low carb, adequate protein and high fat diet.
Like most low carb diets, you are required to drastically reduce your carb intake; however, instead of increasing your protein macro, you increase your fat macro. We’ll get more in depth with macros later.
Ok let me break it down for you.
Glucose. It literally comes from the Greek word for “sweet.” It’s a type of sugar that mainly comes from foods rich in carbohydrates, and your body uses it for energy. As it travels through your bloodstream to your cells, it’s called blood glucose or blood sugar.
Insulin. It is a hormone that moves glucose from your blood into the cells for energy and storage.
If glucose is your main source for energy, then the fats you eat are not needed and therefore stored.
Once you re-evaluate your macros and switch from a diet high in carbohydrates to a low carb, high fat diet such as the Ketogenic diet, you will put your body into a new metabolic state where it will then start to burn fat as the primary energy source and your body will then produce ketones.
Ok, let’s get a little science-y for a second.
The mitochondria within every cell in the body needs to metabolize either glucose or ketones to form ATP (Adenosine Triphosphate), which is an important energy molecule. Thanks to cellular energy metabolism, ketones are able to create much greater amounts of energy per molecule than glucose can, which essentially means the energy source attained from ketones is much more stable and sustainable than that attained from glucose.
Once you have retrained your body to metabolize ketones as the primary fuel source, you have put your body into a state of Ketosis. The goal of a properly maintained Ketogenic diet is to have your body in this metabolic state as optimal ketone levels offer many health, mental performance, physical and weight loss benefits.
